Photokeratoscopes view the reflected image of the black and white concentric rings of a Placido disc, providing qualitative shape information across a large area of the cornea.

Additional displays include cross sections and three-dimensional wire nets..When viewing the output, before looking at the map, it is important to check the patient details and date,
